San Antonio coach Gregg Popovich didn't reveal the lineup change during his pre-game press conference, saying only that he would "probably not" use his same starting lineup from the first four games of the series.

"We're figuring it out right now," Popovich told reporters, less than two hours before tip off.

Bonner, 34, averaged 3.2 points and 2.1 rebounds in 11.3 minutes per game over 61 appearances this season. The 10-year veteran shot 42.9 percent on three-pointers this season.

The change marks the first of this postseason for the Spurs, who had started Parker, Green, Leonard, Duncan and Splitter throughout the 2014 playoffs. The Parker, Green, Leonard, Duncan and Bonner lineup played just 27 minutes together during the regular season and four minutes during the playoffs.
